SUMMARY

The IUPAC name for Al2(Cr2O7)3 is aluminum dichromate, derived from the oxidation states of aluminum (+3) and dichromate (-2). For As2S3, the correct IUPAC name is arsenic trisulfide or arsenic (III) trisulfide, based on the oxidation state of arsenic (+3) and sulfur (-2). Understanding oxidation states is crucial for naming compounds accurately.

PREREQUISITES
  • Understanding of oxidation states in chemistry
  • Familiarity with IUPAC naming conventions
  • Knowledge of polyatomic ions, specifically dichromate
  • Basic principles of chemical formulas and nomenclature
NEXT STEPS
  • Research the IUPAC naming rules for inorganic compounds
  • Study oxidation states and their determination in compounds
  • Learn about common polyatomic ions and their charges
  • Explore examples of naming complex ionic compounds
USEFUL FOR

Chemistry students, educators, and anyone involved in chemical nomenclature or studying inorganic chemistry will benefit from this discussion.

Homework Statement



I don't understand how to do this. There is 2 of them I am not sure of?

1st: As2S3 - Is the correct IUPAC name: DiAresenic Trisulfide?

2nd: Al2(Cr2O7)3 - IS it DiAluminum ... Need help with this. How do you get the IUPAC name from this. Any help would be great!



Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
1. Since we know sulfur is in a -2 oxidation state, that means arsenic is +3. So you could call it either arsenic trisulfide or arsenic (III) trisulfide.

2. Aluminum is always +3, and dichromate is always -2, so the name is aluminum dichromate.
 
I am still having trouble with As2S3

How do we know sulfur is in a -2 oxidation state? And how does Arsenic get a +3

How does that turn into Arsenic Trisulfide?

Really appreciate help on this! Thanks.
